POST-CAP.

SPECIFICATION forming part of Letters Patent No. 760,512, dated May 24,1904.

Application led January 30, 1904. Serial No. 191,298. v(No model.)

To ttl whom, it may concern.-

Be it known that I, ALFRED S. ALscHULER, a citizen of the United States,residing' at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Post-Caps, of which thefollowing is a full, clear, concise, and exact description.

My invention relates to building construction, and more particularly toa post-cap or connection for supporting girders and joists where theyabut against vertical posts.

I will describe in detail certain preferred embodiments of my inventionby reference to the accompanying drawings, and the parts, improvements,and combinations which I consider to be novel will be pointed out in theappended claims.

In the drawings, Figure 1 is a side view of a post and girder connectionwith a post-cap of my improved design. Fig. 2 is a transverse sectionalview of the post-cap, the posts and girders being indicated bydotted-lines. Fig. 3 is a perspective view of my improved postcap, theposts and g'irders being shownl in dotted lines. Fig. 4: is a side viewof a post, girder, and joist connection with a four-way post-cap of myimproved design, which is adapted to support the joists so -that theirupper edges will come in the same plane with the upper edges of thegirders. Fig. 5 is a transverse sectional view of the four-Way post-cap,the posts, girders, and joists being indicated in dotted lines. Fig. 6is a perspective view of the four-way posteeap with the posts, girders,and joists indicated in dotted lines. Fig. 7 is a detail perspectiveview showing how the cross-pieces which support the joists mayconveniently be formed.

The same letters of reference are used to designate the same partswherever they are shown.

Referring iirst to the post and girder connection shown in Figs.l l to3, inclusive, the post-cap consists, essentially, of an inverted steelchannel-plate having its horizontal web a adapted to rest upon the topof the lower post b and downwardly-projecting flanges a adapted to`embrace the sides. The ends of `the cap-plate a project beyond thesides of the posts, and I provide end pieces c, of anglesteel ofL-shaped cross-section, which lie across the projecting ends of saidcap-plate. The vertical flanges c c of the angle-bars are adapted to lieagainst the sides of the upper post to prevent the lateral displacementof said upper post, which is seated upon the plate a of the post-cap.the end pieces c c extend outwardly and rest upon the projecting ends ofthe cap-plate a and may be bolted or riveted thereto. The angle-steelend pieces c c are adapted to receive and support the abutting ends ofthe girders e c, the lower corners of which girders rest in the seatsformed by said end pieces. Crossribs f j' are preferably provided inconnection with said end pieces for the purpose of serving as anchorsfor` the girders, said ribs being adapted to lit into notches in thelower edges of the girders. I prefer to form these ribs by turning upthe eXtreme ends of the cap-plate a just beyond the edges of thehorizontal flanges 02 of the angle-pieces c, as this is a cheap andconvenient construction. It is evident, however, that these cross-ribsmay be formed of separate pieces riveted onto the flanges c2, ifdesired. The body portion of the cap-plate, as I have heretofore pointedout, is preferably made of a section of channel-steel; but it is evidentthat it might be made of a bent plate, or instead of the vertical'flanges being formed integrally with the central plate these partsmight be separate pieces suitably united.

I will now proceed to describe the four-way post-cap or connection bywhich the ends of the joists g g, abutting' against the post, may besupported, as well as the gil-ders e e, by the post-cap. A four-waypost-cap may easily be made upon the same principle as the two-waypost-cap by extending the angle-bars or end pieces c c on each sidebeyond the sides of the post and uniting these projecting ends of theangle-bars by cross-pieces /t l1., which will form ledges adapted toreceive and support the ends of the joists g g. The cross-pieces /L Lare preferably made of angle-steel, having the vertical flanges restingagainst the post The horizontal ilanges c2 of and the horizontal iiangesforming ledges or shelves upon which the lower edges of the joists mayrest. The cross-pieces may be supported by the projecting ends of theanglebars c c in any suitable way; but I prefer to form thesecross-pieces, as shown in Fig. 7, of a section of angle-steel, havingthe eX- tremities of the horizontal flange turned down in position tolie against and be riveted to the projecting vertical fianges of theangle-bars c c. It is evident, however, that cross-pieces of other formsmay be employed and that these may be supported in various ways upon theprojecting end pieces o c.

The post-cap of my invention is especially advantageous in that it islight, strong, and easily and cheaply constructed, requiring but fewparts and these of simple forms, which are easily and quickly assembled.

Havingthus described my invention, I claim as new, and desire to secureby Letters Patent, the following:

l. A post-cap comprising a metal cap-plate a, adapted to lie upon thetop of the post, downwardly-projecting anges a a at the sides of saidplate adapted to embrace the sides of the post, the ends of thecap-plate projecting on either side beyond the line of the post,angle-bars oi L-shaped cross-section having horizontal flanges turnedaway from the post, said anges lying across the projecting ends of thecap-plate and being fastened thereto, the vertical flanges of saidangle-bars being adapted to lie against the sides of the upper post,said L-shaped angle-bars being adapted to receive and support the lowercorners of abutting girders, substantially as set forth.

2. A post-cap comprising a metal cap-plate having horizontal anges lyingacross the pro- 1 jectirir ends of the cap-plate and being fastenedthereto, the vertical flanges of said angle-bars being adapted to lieagainst the sides of the upper post, said L-shaped angle-bars beingadapted to receive and supportthe lower corners of abutting girders, andcross-ribs f f formed by the upturned ends of the capplate beyond thehorizontal flanges of said angle-bars, said ribs being adapted to serveas anchors for said girders.

3. A four-way cap-plate comprising a capplate a anddownwardly-projecting flanges a adapted to fit over the top and againstthe sides respectively of a post, the ends of said plate projectingbeyond the sides of the post, angle-bars of L-shaped cross-section,having horizontal flanges lying across the projecting ends of the capplate and fastened thereto, the ends of said bars projecting beyond thesides of the cap-plate, said angle-bars being adapted to receive andsupport the ends of girders, and cross-pieces uniting the projectingends of said angle-bars and supported thereby, said cross piecesJforming ledges adapted to support the ends of joists, substantially asdescribed.

In witness whereof I hereunto subscribe my naine this 27 th day ofJanuary, A. D. 1904.
